The heatwave is expected to break Welsh records, with the temperature expected to top the 35.2C (95F) mark.

That record was set at Hawarden, Flintshire, in August 1990, and south-east Wales is likely to be the hottest spot on Wednesday.

But while it will slowly turn cooler by Thursday, there could be local thunderstorms and humidity will rise, making it more uncomfortable.

Meanwhile, firefighters in several areas dealt with hillside gorse blazes.

The Wales-England border with England is most likely to see the new record.

HAVE YOUR SAY

I love this weather, Saturday was spent going up Snowdon and admiring what a beautiful country I live in, then the evening was spent having a bbq (loads of beer after the hike) with family and friends. HEAVEN!!!!
